Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642996, here are decompositions:

7 + 8642989 = 8642996
139 + 8642857 = 8642996
157 + 8642839 = 8642996
223 + 8642773 = 8642996
463 + 8642533 = 8642996
487 + 8642509 = 8642996
547 + 8642449 = 8642996
613 + 8642383 = 8642996

Showing the first eight; more decompositions exist.
